FLOATING FILTER.

SPECIFICATION forming part of Letters Patent No. 291,285, dated January1, 1884.

Application filed July 23, 1883. (N0 model.)

To all wit/mt it may concern:

Be it known that I, JOHN H. BREESE, a citizen of the United States ofAmerica, residing at Davenport, in the county of Scott and State ofIowa, have invented a certain new and useful Improvement in \VaterDrawing and Filtering Apparatus, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention appertains to make and use thesame,'reference being had to the accompanying drawings, forming a partof this specification.

This invention relates to apparatus for drawing water from tanks,cisterns, wells, or other vessels or bodies without surplus floatings orsediment.

The objects of the invention are to adapt the apparatus for applicationto narrow cisterns or wells, to enable the filter, forming a part of theapparatus, to float freely in the body of water in which it is placedand maintain an upright position therein, and to improve theconstruction of the filter, so as to secure a thorough filtration of thewater drawn from the tank or well.

Figure 1 of the drawings is a vertical section of a tank or cisternprovided with this improved apparatus. Fig. 2 is an elevation, partly insection, of the improved filter form- Fig. 3 is a transverse section ofsaid filter on line 3 3 of Fig. 2.

A represents a tank, cistern, well, or other body of water, located atany convenient point. A pump, B, is connected with this cistern by meansof a suction-pipe, C, which extends into and near the bottom of thetank. This pump may be located directly over the body of water, or atany desired point. Aflexible hose, D, of india-rubber or other suitablematerial, provided with couplings at both ends, is connected at one endto the lower end of the pipe 0 and at the other end to the lower end ofthe floating filter E. The floating filter E ispreferably composed of anouter perforated cylinder, E, a smaller cylinder or pipe, E, arrangedvaxially within the outer cylinder, and divided by a wire-gauze orperforated metal diaphragm, or into an upper perforated chamber, a, anda lower imperforated chamber, 1), and an air-chamber, E, at the upperend of said cylinders. The outer cylinder, E, is provided with a bottom,(I, the inner cylinder being cast integral therewith or attachedthereto. The inner cylinder is provided near its lower end with anotherwire-gauze or perforated metal diaphragm, e, and below said diaphra-gniwith an interior screw-thread adapted to receive the coupling of theflexible pipe, which connects with the suction-pipe. The outer cylinderis provided with an inner lining of wiregauze, f. This cylinder isconstruct ed from a sheet of perforated brass and a sheet of wire-gauzelaid over the same, the'said sheets being-bent into a cylinder, themeeting edges of which are turned outward, the wiregauze overlapping thejoint, the parts being then united by means of solder, as clearly shownin Fig. 3. The solder enters the meshes of the gauze and readily unitesthe parts, forming a strong joint. The annular space between the innerand outer cylinders is filled with charcoal or any other suitablefiltering material. The inner cylinder is also preferably lined in partwith wire gauze, and its upper perforated compartment, a, is filled withsponge, and its lower compartment, 1), is filled with silicious sand.

The air-chamber E" consists of a hollow cylinder, having a tight headand a tight bot tom, the bottom being above the lower edge of thecylinder, and provided with a short tube or neck, 71, screw-threaded tofit the upper screw'threaded end of the inner cylinder, E or these partsmay be united in any other suitable manner. When the parts are united,the bottom of the air-chamber forms the top of the filtering-cylinders,the lower edge of ill the air-cylinder shutting down over the upper edgebf the outer filtering-cylinder. The head of the air-chamber is providedwith a handle, g, by which the filter may be readily lifted whendesired.

The operation of this invention is as follows: The filter is connectedwith the lower end of the suction-pipe, near the bottom of the tank orwell, by means of the flexible tube or hose, and float-s freely in thewater, being buoyed up by the air contained within its airchamber, theamount of air being just sufficient to sustain the filter, so that thetop openings in the outer cylinder will be a short distance below thesurface of the .water. The flexible tube allows the filter to maintain alining the cylinders prevents the filtering material from clogging theperforations therein.

The flexible pipe admits of the application of the apparatus to wells orreservoirs of small diameter, since it may rise vertically near thesuction-pipe.

\Vhat is claimed as the invention is- 1. The combination of a cisternwell, or reservoir, a pump, a suction-pipe connecting said reservoir andpump, a floating filter consisting of an air-chamber and two concentriccylinders of different diameters, the outer cyl inder being perforatedthroughout its circumference, and the space between the cylinderscontaining filtering material, and a flexible pipe connecting saidfilter and suction-pipe, substantially as described.

2. A floating filter consisting of an airehamber and two concentriccylinders of different diameters, the outer cylinder being perforatedthroughout its circumference, and the inner cylinder divided by awire-gauze diaphragm into two chambers, one of which is perforated, thesaid chambers and the annular space between the cylinders being filledwith filtering material of different kinds, substantially as described.

3. A filter-casing consisting of a cylinder of perforated metal having alining of wiregauze, the meeting edges of said cylinder being turnedoutward and overlapped by the wire-gauze lining, and united by means ofsolder, which enters the meshes of the outturned wire-gauze lining,substantially as described.
